The Lowdown

Alright, Rusty here. Let’s look at what we’ve got for Kennebunk Beach. I gotta be straight with you – the next couple of weeks are looking pretty flat and frustrating. The overall pattern is small, weak, and messy. There are no real standouts, not a single day that I’d call good. We’re looking at a long stretch of tiny waves and poor conditions. The first real pulse of any size doesn’t show up until the very end of the forecast window.

Right now, and for the next several days, it’s a bust. The water temp is around 68.4°F, which is a touch warmer than normal for this time of year, but that’s about the only good news.

Let’s walk through it. Sunday the 9th, we’ve got a tiny 1.3ft SSE swell with a short 7-second period – barely a ripple. The wind is a cross-onshore from the WNW at 9 mph, making it choppy. The combined energy is weak (20), and the surf is poor.

Monday the 10th through to the middle of the next week is a write-off. The swell drops to 0.3ft and 0.7ft, with periods all over the place but mostly short. The wind is cross or cross-onshore, and the combined energy barely registers, staying in the single digits or low twenties. Every single entry says “poor surf conditions.”

There’s a brief moment on Friday afternoon the 14th and Saturday morning the 15th where the wind goes glassy, but the swell is still only 1.0ft with weak energy (15-20). It’s flat, even if it’s pretty. By Saturday afternoon, the wind swings onshore and ruins it again.

The weekend of the 16th and 17th sees a little more activity. Sunday the 16th afternoon has a 3.3ft south swell, but it’s a short 4-second period, and the wind is a fresh cross-onshore at 22 mph with heavy rain. The energy is still low (36). That’s a mess, not surfable.

Monday the 17th afternoon is where things get a tiny bit interesting. A 3.0ft SSE swell with a 6-second period, but the wind turns cross-offshore from the NNW at 13 mph, making it clean. The combined energy jumps to 111 (moderate). This is the closest we get to a decent window, but the swell is still weak and the period is short. It’s a long shot.

Tuesday the 18th has a glassy morning, but the swell is only 1.3ft, and while the period is a long 15 seconds, it’s too small to do anything with. The energy is 92. By afternoon, the chop is back.

Then we get a few days of onshore wind and small, weak swell. Wednesday the 19th afternoon has a 4.3ft south swell, but it’s a 5-second period with onshore wind – just a lumpy mess with moderate energy (198). Thursday the 20th morning goes glassy again, but the swell is only 1.6ft.

The only real spike in size comes on Saturday the 22nd afternoon. We get a 5.2ft south swell with a 6-second period. The wind is a cross-shore from the SE at 9 mph. The combined energy is 183 (moderate). It’s still a short-period, wind-affected swell, so it’ll be a bit bumpy and not really well-shaped. This is the biggest swell of the whole run, but the quality is still poor. It’s not going to be clean.

For a sheltered beach break like Kennebunk Beach, with this combination of small, short-period swells and mostly onshore or cross-winds, this setup honestly looks more interesting for kite surfing than paddle surfing. There just isn’t the wave energy or the clean conditions for a decent surf.

In summary, it’s a long, dry spell. Don’t get your hopes up. The 17th afternoon and the 22nd afternoon are the only times where there’s enough water moving to even think about it, but the quality just isn’t there. We’ll have to wait and see if the forecasts change for the better.

Information about the Kennebunk Beach Surf forecast

The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
